I am new to the iphone and just made my first attempts at jailbreaking.I ahve 2 phones here. I used this writeup: Step-by-Step Guide to Jailbreak iPhone 3G using QuickPwn (Windows) - iPhone Hacks and it worked flawlessly on the first phone. But everytime I try to jailbreak the 2nd iphone quickpwn tells me it has encountered an error and it closes. I even attempted it on a 2nd computer and I get the same error. Im following the exact same steps for both and they are the same models witht he same firmware ect.
It didnt give a number IIRC it just said it encountered and error and had to close. I got ti to work today, I reset the phone to prepare it for a restore using itunes but I just cancelled the restore and closed itunes. It worked fine after that.
